Full sleeve vibration soil sampling prefabricating pouring composite pile construction method
The invention provides a full sleeve vibration soil sampling prefabricating pouring composite pile construction method which comprises the following steps that an outer sleeve and an inner pipe are submerged into a soft soil layer through high-frequency vibration, soil gradually enters the inner pipe, the outer sleeve and the inner pipe are submerged to a designed height, the inner pipe is vibrated or directly pulled out, the soil and the inner pipe are lifted, the soil is vibrated, the pile sinking construction of a prefabricating pile is hammered by a pile hammer or conducted by static pressure, a steel reinforcement cage is placed at the top end of the prefabricating pile, concrete is poured into the steel reinforcement cage, and the outer sleeve is pulled out through the high-frequency vibration. The pouring pile is short in length, the pile body concrete quality is convenient to control, the prefabricating pile is hammered in a hard soil layer, the bearing force of the pile body is greatly improved, the quality is more reliable, and the influence of soil-squeezing on nearby buildings and road pipelines and the pollution of slurry to the nearby environment during construction are avoided.
